@1779789201 i am just another user, and i have a few inquiries:

  • what’s the material applied?

  • have you changed any of the render settings or is this what you see using the default setting?
  • which IS version are you using?

I recently encountered a similar issue. When I set the material of an object to OmniGlass, I can see that the object has a transparent effect. However, when I place a light source in front of these objects, I can see a very deep shadow behind the glass, which is exactly the same as the shadow when the object is set to OmniPBR. It seems like the lig

These shadows can be improved by adding “Caustics” to the rendering engine.

Hello, I encountered a similar problem. This is my transparent object USD file. I use vscode for development. I imported this USD file and simulated the data, but I encountered a problem. The generated image has shadows. If it is as shown, what should I do? In other forums, I tried rep.settings.set_render_pathtraced() and rep.settings.set_render_rtx_realtime() in the code, but they didn’t work. What should I do? I look forward to your reply. Thank you.

And you mentioned adding Caustics to the engine, how can I add it in the code?

Yes that is certainly a low “trace depth” number, meaning you are not allowing the light to bounce in and out of the glass enough times before final termination (going black). So you need to increase your trace depth. I am not sure of the command for that.
